Realistic Playback

This may be posted in the wrong forum, so please if it is I would appreciate direction to where I can get my questions answered best.

I am taking the piano accompaniment for a choral pieces and arranging it for a small chamber ensemble. However I do not have the actual players for the esnsemble so I would like to play it back as realistically as possible for accompanying a choral group. I am using Fianle 2004 to create the arrangement but I am not thrilled with the playback that I get with Fianle. What else is available that I can use for better performance playback? Or are there techniques that I can use to get Fianle to have a more realistic playback? And what about sounds? Can I get Fianle to playback in something better sounding that MIDI?

I use Finale quite a bit for entering music and such, however my skills are pretty limited when it comes to playback. Any help would be appreciated.
